The tablet market is predicted to reach 234.5 million units in 2015, and will see 2.1 percent year-over-year growth from 2014 over the next five years, according to the IDC research group. Google Android-powered devices accounted for 67.3 percent of the tablet market, shipping 154.7 million units, compared to the Apple iPad (27.6 percent) with 63.4 million units shipped.

However, Microsoft Windows, which ended 2014 with just 5.1 percent market share, will reach 7 percent in 2015 - could reach 14 percent by 2019. Manufacturers embracing Windows 10 will help push shipment volumes from 11.6 million in 2014 up to an estimated 38 percent in 2019.

"Microsoft is doing a lot of good things right now and we believe the launch of Windows 10 later this year will not only have a significant impact on Microsoft's share of the market, but on the industry as a whole," said Jean Philippe Bouchard, Research Director of Tablets at IDC. "There is an appetite for a platform that can provide a productivity experience that remains consistent across multiple form factors and device types, and we believe Microsoft is well positioned to capture some of that demand."
